1. A temperature compensated RRAM sensing circuit to improve the readability against temperature variation, the circuit comprisinga) a temperature dependent memory resistor array;

  • b) a temperature dependent element;

    c) a temperature compensated reference circuit in communication with the temperature dependent element and to provide at least one temperature dependent reference signal; and

    d) a comparison circuit in communication with the memory resistor array and the temperature compensated reference circuit,the comparison circuit adapted tocompare at least one sense signal developed by at least one memory resistorwith at least one reference signal developed by the temperature compensated control circuitand to provide at least one output signal in response to the comparison.
